Drought And Coyotes Mediate The Relationship Between Mesopredators And Human Disturbance In California, Molly K. Parren Jan 2019

Drought And Coyotes Mediate The Relationship Between Mesopredators And Human Disturbance In California, Molly K. Parren

Cal Poly Humboldt theses and projects

Mesopredators in California are facing two major changes to their ecosystem: drought and the expansion of human disturbance. As a result, mesopredators are likely shifting their habitat use as well as their interspecies interactions to balance resource needs and risk-taking on the landscape. In response to severe drought, the California Department of Fish and Wildlife deployed 585 camera traps throughout the Mojave Desert and Central Valley documenting mammalian mesopredator presence in a drought year (2016) and a post-drought year (2017). The objectives of this study were to examine spatial patterns of mesopredator occurrence and co-occurrence with a dominant predator, the …


Elucidating Patterns Of Bat Species Occupancy Across A Disturbed Landscape In California's Central Valley, Trinity N. Smith Jan 2019

Elucidating Patterns Of Bat Species Occupancy Across A Disturbed Landscape In California's Central Valley, Trinity N. Smith

Cal Poly Humboldt theses and projects

California’s Central Valley, one of the most productive agricultural regions in the world, is home to 14 species of resident and migratory bats. The Central Valley has been identified as a crisis ecoregion, and a high number of species are at risk due to anthropogenic land use. In addition, the Central Valley has faced severe drought, effects of which are intensified on the natural landscape by agricultural irrigation practices. In response to the historical drought of 2012-2015, California Department of Fish and Wildlife (CDFW) implemented the Terrestrial Species Stressor Monitoring (TSSM) project, which in part aimed to collect information on …
